Wish I could have afforded more. haha.
Some of it was just not knowing what I could and couldn't buy with my IRA when I started it. I stayed mostly with mutual funds (no trade fees), and as long as you could get over the min order, you could buy fractional shares.
I didn't realize I could buy any straight up stock as well, just paying the $7.95 (we won't call it $8) fee, at first.
